Alistair MacLean's UNACO: Prime Target

A US government official is assassinated, a list of names, all male, all German, is found and two men on the list are already dead. What is the connection? When the mission looks impossible, who do you call? UNACO. A young American government employee is murdered in cold blood on a London street. Her death is only the tip of a conspiracy that threatens the life of Andreas Wolff, the computer genius responsible for the security codes for ICON - the computerized criminal identification network. Malcolm Philpott, the nigmatic and powerful head of UNACO, recognizes the grave threat, and assigns his two best agents to the case. Sabrina Carver and Mike Graham must race from New York to London, Morocco and Berlin in their efforts to crack the lethal intrigue that threatens world security and has its roots in the final days of World War Two and the desperate plans of a dying madman.
